Shortly after the 5-month mark of your relationship, you start to realise that your other half isn’t as perfect as he or she once seemed. They actually seem a little … immature. While a little spontaneity is always fun and spices things up, constantly juvenile behaviour may hint at something much more sinister: That your partner hasn’t quite grown up yet. If you feel like you’re constantly on different chapters of the life book (you being on maybe page 25 and him/her being on page 14), then read on!

Does your partner constantly play the silent game to get his way? Does he or she do it in a totally serious manner? If so, a) that psychob*tch is manipulative, and b) incapable of constructive self-expression – the first sign of childishness.

If the above quote is practically the opposite of your partner’s life philosophy, then you need to re-evaluate your relationship ASAP. If your partner is always picking fights over the “small stuff”, it probably means they don’t have the capacity to evaluate whether the eventual argument is worth it.

Your partner always has to have the last say in any argument, and his or her last say is always something that completely misses the point or something that is irrational and ridiculous. Sounds familiar? Sign of immaturity: your partner is too emotionally immature to process the logic beyond the heat of the argument.

One word: Seriously? Fart jokes and laughing at people who trip over their own feet by accident?Most people outgrow them when they start secondary school. Although, if that’s your thing too, then hey, by all means.

You know how your teachers have always told you that whatever you say says more about you than the person you say it to/about? Your partner being rude just says that he or she is childishly self-centered – so much that they cannot empathise with how they make others feel.

If your partner gets unjustifiably jealous all the time, it could mean a) that he or she has unresolved insecurities, has yet to blossom into a confident, self-assured individual, and needs more time for personal development, b) he or she doesn’t have sufficient emotional maturity to understand that they have to place trust and faith in you for a solid relationship or c) both.

If your partner still acts like a child, you can try to stick it out and aid him or her in the path of personal growth. However, if there is a huge existing gap in maturity, it’s probably not worth the time and effort – you’ll find yourself treating your partner as inferior, and both parties will quite possibly end up resenting each other.
